2 Questions conc. GTA IV PC

Hello,

Although a non-RPG i really like this game, however at about 50% completion i have two problems....

1. Due to having stopped playing it for a week, i totally forgot which button i have to press on the keyboard for calling or hailing a cab (which leads to Niko whistling)... I haven`t found it in the manual either......

2. Where are the stupid helicopters... I want to land on top of a skycscraper for a clean-up missio, however the heli-tours place in algonquin is empty, i never seem to see one landed chopper and i also cannot take my GF out to that place......I know brucie has one, however as i am inside the mission i cannot call him to "borrow his helicopter....


Can anyone help me ?

Cheers,
L.

When you see a cab, press and hold down "F" key; or just call your cousin Roman and select "Car Servide" option, he will send someone to transport you.

Can't answer the second question as i am still early in the game.
